  Materials which contain polysaccharide chains, particularly alginate or modified alginate chains. The polysaccharide chains may be included as side chains or auxiliary chains from a backbone polymer chain, which may also be a polysaccharide. Further, the polysaccharide chains may be crosslinked between side chains, auxiliary chains and/or backbone chains. These materials and non-modified or otherwise modified alginate materials are advantageously modified by covalent bonding thereto of a biologically active molecule for cell adhesion or other cellular interaction. Processes for preparation of these alginate materials and methods for using them, particularly for cell transplantation and tissue engineering applications.
